General Information about Ultramarine

The hex color #01159A, commonly known as Ultramarine, is a deep and saturated shade of blue. It belongs to the blue color family and is characterized by its strong presence and association with depth and stability. In the RGB color model, #01159A is composed of 0.4% red, 8.2% green, and 60.4% blue. This color is often used to evoke feelings of trust, loyalty, and intellect, making it a popular choice for branding and corporate identities. Historically, Ultramarine was derived from the mineral lapis lazuli, making it a prized and expensive pigment, particularly during the Renaissance. Its rich hue made it a favorite among artists for depicting important figures and scenes. Today, synthetic pigments allow for more accessible use of this vibrant color in various applications, from digital design to physical products.

The color #01159A, a deep ultramarine, presents specific accessibility challenges, particularly concerning color contrast. When used as a foreground color, it necessitates very light text (white or near-white) to ensure sufficient contrast for readability, meeting WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using this color for large blocks of text might cause eye strain due to its high saturation. It's more suitable for decorative elements, highlights, or accents rather than extensive textual content. In user interface design, pairing it with lighter shades of blue or complementary colors like yellow can create visually appealing and accessible experiences. Testing with color contrast analyzers is crucial to confirm accessibility compliance and ensure inclusivity for users with visual impairments. Consideration should also be given to users with cognitive disabilities, as highly saturated colors can sometimes be overwhelming. Overall, thoughtful application and proper contrast adjustments are vital for making #01159A accessible.
